Uriage Eau Thermale Serum Booster with 1.5% Pure & Natural Hyaluronic Acid | 86% Plumped Skin

Experience a fresh, plump lift in a single step

Uriage Eau Thermale Serum Booster is a lightweight, three-in-one serum designed to hydrate, plump, and smooth the skin. In a small use test, 22 volunteers over 21 days reported an impressive visible plumping effect, with 86% noting changes in skin fullness. The formula absorbs quickly, leaving a soft, peachy-smooth feel without a sticky or greasy afterglow.

Key ingredients work together to support hydration and resilience. A 1.5% blend of pure and natural hyaluronic acid helps support surface moisture and a supple feel, while marshmallow flower adds a hydrating and antioxidant touch. The result is hydration that endures and a complexion that invites touch with a gentle, fresh texture.
